Thanks to NetGalley and Quercus for the ARC of this book.

This is one of the best thrillers I have ever read. It is both absolutely compelling and excruciatingly painful to read. It is brilliantly written and deftly covers so many sensitive issues. I’m absolutely in awe at the author’s skill in writing something so fast-paced and thought-provoking.
It is the story of Pete and Maddie who discover the two year son they have been raising was swapped in the hospital and their biological son is being raised by another family. The book follows their attempts to have a civil relationship with the other couple and find an arrangement which is best for both children. However, it is not long before things start to go horribly wrong.
I could not put this book down! It was uncomfortably fascinating to imagine yourself in their position and what you would do if you had to choose between the child you have loved for 2 years and your biological child.
Delaney descriptions of the difficult situations which parents find themselves in including emergency C-sections, neo-natal care, postpartum psychosis and dealing with violent children and brilliantly drawn and very realistic. I found so much of the book fascinating and moving.
I cannot recommend this book highly enough. Go and read it!
